Uh I think your comprehension of the English language isn't high enough. Former Argentine Star refers to him being a star in Argentina.
It doesn't mean he's no longer Argentine - it means he's no longer a star Argentine player because he plays in the NBA now.
I don't know how old you are or what is your overall understanding of the English language, but the article is referring to "Argentine star"....as in he was a former "Argentine star". Thus meaning he's no longer a star in Argentina due to his commitment now to the NBA.
If Nocioni doesn't get injured,I'm quite sure he will be on the Argentinian team for the Olympics. Since he didn't participate in the recent qualifying tournament and has been playing NBA ball,he is being referred to as a former Argentinian star.
